Good morning to all judges, teachers, fellow contestants andaudiences. I would grasp this honour today to tell about Water, water is the most imp thing on earth. without water no life. We take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles. And still, today, nearly 1 billion people in the developing world don’t have access to it. Clean, safe drinking water is scarce. It is the foundation of life, a basic human need. Yet today, all around the world, far too many people spend their entire day searching for it.
Simply put, water scarcity is either the lack of enough water (quantity) or lack of access to safe water (quality). It’s hard for most of us to imagine that clean, safe water is not something that can be taken for granted. But, in the developing world, finding a reliable source of safe water is often time consuming and expensive. This is known as economic scarcity. Water can be found… it simply requires more resources to do it. In other areas, the lack of water is a more profound problem. There simply isn’t enough. That is known as physical scarcity.
The problem of water scarity is a growing one. As more people put ever increasing demands on limited supplies, the cost and effort to build or even maintain access to water will increase. And water’s importance to political and social stability will only grow with the crisis. In some places, it is simply dry. Water is hard to find. In others, this most critical need is literally only a few feet below ground waiting to sustain life. The Importance of Water There’s no doubt that water is important. Not only do we humans use it just about every day, but every living thing needs it to live.
It has helped form the Earth as we know it, and it covers over 70% of the Earth. Even where there is land, much of it is covered in ice, which is obviously just solid water. The importance of water is clear to us in many ways, and we can’t overlook it. Where would people be without water? Well aside from, you know, not being alive, we may never have evolved the big brains that make us such a unique species. Some say that that learning how to keep, and transport water over land was the key to our survival when other similar species just kept dying off. How about the importance of water in shaping the Earth?
At some point or another it is likely that where you are sitting right now was covered in water. It may have been under the vast oceans that once spread further than they do today, or they may have been buried under as much as a mile of glacier. Glaciers formed the largest lakes; the Great Lakes, and they are responsible for carving mountains into the shapes we know. Did you know that water is also a large part of weather patterns? Aside from actually being part of the weather in the form of rain sleet and snow, large bodies of water can keep a regions temperature milder than a location even just a few miles inland.
Humidity is also a large factor in weather. Humidity is the amount of the water in air. This can affect the temperature of the air close to a body of water. When the temperature of the air in one place is different from that in another, you will also find a difference in pressure. Differences in pressure causes atmospheric movement and weather fronts. While water is not the cause of weather, you can clearly see the importance of water in the equation. We take advantage of our access clean drinking water.
Most of us go to the faucet and get a glass of clean fresh water several times a day and never give the first thought to the importance of water. We have become so accustomed to having it, we rarely think about what our lives would be like, if we had to struggle to find water that was even halfway safe to drink. Sadly, in many other countries across the globe, this a problem that is all too real for it’s inhabitants. They are forced to drink water from rivers, streams, watering holes, and other water sources, that are more than likely diseased or polluted. They are forced, often times, to bathe and cook with this same dirty water.
Imagine what it would be like if all the water that you had available, was water that you were sure was going to make you sick to drink. What would it feel like to have to give your children this water, knowing that it could endanger their health, or even their life. What a helpless situation this would be. It is heart wrenching too even think that there are people that deal with this every single day of their life We’re mostly water, with some trace minerals. The Earth should be called The Water, as most of its surface is covered by water. One can go about 30 days without food – but about three with water.
Most of the world’s oxygen is generated by algae in the water. Water is the most important enabler of weather systems (the Sun drives everything, obviously). In the past, bitter wars have been fought over water resources – and in the future, this will likely happen more as well. We came from water; one could bottle salt water, sterilize it for microorganisms, and put it directly into someone’s veins as an emergency blood expander. We’re born mewling, defenseless infants – but whereas we won’t walk for many months, we can swim instinctively at a very early age.
